Method for quantitative absorption spectroscopy

14 Aug 2006 (Updated 18 Sep 2009)

A computational method for quantitative analysis by multiwavelength absorption spectroscopy

File Information
Description	A computational method for quantitative analysis by multiwavelength absorption spectroscopy, called the Tfit method, based on fitting a model of the instrumentally-broadened transmission spectrum to the observed transmission data. It has the advantages of wider dynamic range and greatly improved calibration linearity, compared to conventional methods. Run DemoTFit.m to see how it works. Several other demos are included to allow exploration of the capabilities and limitations of this method. See http://www.wam.umd.edu/~toh/spectrum/TFit.html for more details. (Thanks to Matthew Jones for the slider function.)
